摘　　要：随着分布式电源规模化应用,如何实现其自描述和互操作是即插即用信息交互技术的难点。根据IEC61850通信模型及规约映射,可建立分布式电源即插即用信息交互机制。该交互机制以终端层设备的信息建模与自描述配置为基础,通过对IEC61850及IEC61970/IEC61968拓扑模型的扩展来消除主站与终端模型间的异构问题;由异构模型映射与数据转换模块进行终端IEC61850信息与主站IEC61968消息的交互数据转换,形成主站层与终端层间的信息交互通路;建立由监控主站、配电终端、通信网络三部分组成的即插即用信息交互架构。设计含储能电站的配电网馈线算例,通过一致性测试验证终端自描述配置信息与主站信息交互机制的有效性。With the large-scale application of distributed generators, how to realize self-description and interoperability is a difficult point of plug-and-play information interaction technology. According to the IEC61850 communication model and protocol mapping,a plug-and-play information interaction mechanism of distributed generators is constructed.The mechanism is based on information modeling and self-describing configuration of the terminal-layer devices.The heterogeneity between the model of master stations and terminals is eliminated by extending the IEC61850 and IEC61970/IEC61968 topology models. The heterogeneous model mapping and data conversion module performs interactive data conversion between the IEC61850 information and the IEC61968 message, so that an information pathway is formed between the terminal layer and the primary station layer.A plug-and-play information interaction architecture is established, which consists of three parts: monitoring main station, power distribution terminal and communication network. Taking the distribution network feeder segment with BESS as an example,the consistency test is conducted to verify the validity of the self-describing configuration information and the interaction mechanism.
